Dovetail Live Routes And Mastery

I do not own all routes on PS5: i own 63 actual routes, ignoring Training Centre.

My mastery page has 61 actual routes

I know one that is missing, but must i make out those two lists and compare ?

Could an intern do that on a DTG PC ?

And should that PC list match the PS5 list ? Should we know that before we go adding posters and i know not what ?

This is not a suggestion. Is this a known thing ?
